Life often presents people with various surprises. They can be both positive and negative. Clary Frey is no longer a teenager. She turned the coveted 18 years. Now she is an adult. The heroine decides to celebrate her coming of age in the company of Simon's best friend, in one of the local clubs. She did not think that on this day her life would change forever.
Being indoors, the heroine drew attention to three guys who performed a strange ritual, similar to the capture of a monster. What she saw shocked her. After finding out from her friend whether he saw what happened or not, Frey decided that she had some mental problems.
Returning home, the lady told her mother everything. The woman realized that she could no longer hide the truth from her daughter. The lady told the girl that she was not an ordinary person, the blood of a Shadowhunter flows in her veins. The heroine belongs to one ancient family. Her duty is to become a hunter and, like all hunters, engage in the extermination of evil entities. Before embarking on such work, the girl must undergo some training. She still has absolutely no experience to calmly enter into fights and hope for a positive outcome.
